First question: 40A is current, which means 40A. Power = current × voltage, the voltage of household electricity is 220V, and the maximum current of your meter can withstand 40A, so the maximum power of your meter can reach 8800 W, which is 8.8 kW. If the air conditioner is 1 kW, eight air conditioners can be turned on at the same time.

In fact, the current of the electric meter is not necessarily the maximum current of your home, and it may be limited by the master switch and leakage protector (most families have switch boxes). If the rated current of control switch and leakage protector is small, you don't need 40A, that is, you can't reach 8.8 kW. If it is exceeded, it will trip.

The second and third questions: the room smells big, mainly because the paint and board contain formaldehyde, benzene and other substances, so you can open the doors and windows for ventilation. The smell in the paint will decrease rapidly in a few days. If it is the smell emitted by wooden boards or floors, it belongs to the slow-release type because it is closed. Besides paying attention to ventilation, some measures can be taken to reduce pollution. For example, as mentioned above, make a little onion and chop garlic and put them in the room. You can also put some vinegar in the bowl or some salt in the bucket. Of course, there are also companies that provide services to remove decoration pollution. You can also try it. In addition, some plants can be placed. The following excerpts are about how plants reduce pollution:

Chlorophytum can eliminate more than 80% of harmful gases released by indoor decoration materials, ivy can absorb formaldehyde, and aloe can absorb carbon dioxide at night ... Do you know? Plants also have a good effect on purifying indoor environmental pollutants. And this effect has been confirmed by professional testing institutions.

However, which plants can be used for purification, which plants have better purification effect, and how to calculate the number of plants in the room? Many consumers are not very clear.

Experts remind consumers that when using plants to purify formaldehyde pollution in indoor environment, they should pay attention to:

1. Plant decontamination can choose medium and low pollution: generally, in the environment where indoor environmental pollution is light and moderate, and the pollution value is less than 3 times of the national standard, plant decontamination can achieve better results.

Second, according to the different functions of the room and the size of the area, choose and place plants. Generally speaking, it is more appropriate to put two pots of plants with a height of 10 square meter in a room with a height of10 meter. Too many plants should not be placed in the bedroom, which is not conducive to sleeping at night; The bathroom can be placed with shade-tolerant and moisture-tolerant plants such as green radish and rich bamboo; This study is suitable for elegant plants, such as Anthurium andraeanum and orchids; Tall plants such as sundew and rich trees can be placed in the living room; Kitchen should be placed cactus and other small plants resistant to lampblack.

Third, there are four taboos in using flowers and plants to purify the indoor environment.

Avoid fragrance: some flowers and plants are too fragrant, which will make people uncomfortable and even have adverse reactions. Such as cordate telosma, tulip, five-color plum blossom and other flowers.

Susceptibility: Some flowers can cause allergic reactions. Like Chinese rose, jade clove, five-colored plum, hydrangea, geranium, bauhinia and so on, when people touch it, it often causes skin allergies and even rashes, which is unbearable.

Avoid poison: some ornamental flowers are poisonous, so we should pay attention to their placement, such as mimosa, poinsettia, oleander, rhododendron and Zhuangyuanhong.

Avoid injury: for example, cactus plants have spikes, so try not to put them in families or children's rooms with children. In addition, for the sake of safety, the plants in the children's room should not be too high, and the flowerpot bracket with poor stability should not be selected to avoid harm to children.
